Towards field trace metal speciation using electroanalytical techniques and tangential ultrafiltration
(2016-05-15)
In this work we propose a trace metal speciation methodology to determine the total, free and ultrafiltered (<1 KDa) metal fractions using electrochemical methods (SCP and AGNES) and tangential ultrafiltration (UF) experiments ...

Interaction between humic substances and metallic ions: A selectivity study of humic substances and their possible therapeutic application
(2007-09-06)
The complexation capacity of humic substances extracted from peat samples taken from the Mogi River in Ribeirao Preto, SP, Brazil, was determined using metal ions (Al(III), Pb(II), Cr(VI) and Cd(II)), yielding the following ...

A single serine residue determines selectivity to monovalent metal ions in metalloregulators of the MerR family
(American Society for Microbiology, 2015-05)
MerR metalloregulators alleviate toxicity caused by an excess of metal ions, such as copper, zinc, mercury, lead, cadmium, silver, or gold, by triggering the expression of specific efflux or detoxification systems upon ...
